COMPOUND FOR EXTINGUISHING FIRES.

SPECIFICATION forming part of Letters Patent No. 366,126, dated July 5, 1887.

Application filed one 8, 1886. Serial No. 204,519. (Specimens) 1'0 aZZ whom, it. may concern:

Be it known that we, EMLEN G. PENROSE,

HARVEY S.NUTiING,al1d WILLIAM H fimlm,

tion of ingredients, substantially as hereinafter full y set forth and claimed.

In the preparation of our fire-extinguishing compound we take carbonate of potash, two parts; carbonate of magnesia, one part; saltpeter, two parts; saleratus, two parts, and sulphate of iron, two parts. These ingredients we dissolve in water intoa liquid, which we place in glass bottles, preferably of globe shape. By throwing a bottle containing this compound into a fire the bottle will immediately or eventually break, by reason of the heat of the fire, causing the compound to spread itself, and the vapors arising therefrom will quench or entirely extinguish the We are aware that each of the ingredients of our compound is old for the purpose; but when combined as herein specified a new and better compound is obtained. 7

Having thus fully described our invention, whatwe claim, and desire to secure by Letters Patent, is-

A fire-extinguishing compound composed of carbonate of potash, two parts; carbonate of magnesia, one part; saltpeter, two parts; saleratus, two parts, and sulphate of iron,two parts, as specified.

In testimony whereof we affix out-signatures in resence of two witnesses.
